Electric Bike (eBike) FAQs

Frequently Asked Questions.

Below are some common questions we get in regards to Electric Bikes (eBikes):

What are the advantages of eBikes with fat tires?

The advantage of using fat tires on electric bikes (eBikes) are:

  1. Performance / Traction – Because of it’s wide surface area, fat tires glide over water, ice, sand, gravel, thick grass, asphalt (pavement) and concrete.
  2. Comfort – Because fat tires are only inflated between 6-25 PSI, they absorb a large amount of shock from hard surfaces which would normally be taken by your spine. Fat tires provide unrivaled comfort and stability in the summer and provide a shock absorbing and comfortable feel when riding on hard surfaces such as asphalt (pavement) and concrete.
  3. Electric Motors – Using pedal assist or our precise throttles makes pedaling fat tire e-bikes a breeze and an easy choice over narrower tires.
What does amp hours (Ah) mean for an electric bike (eBike) battery?
Amp-hours (Ah) indicates the capacity of your eBike battery. Ah is a measure of how much current your electric bike battery can deliver in one hour at your battery’s voltage. For example, an Electrified Mobile long range 21Ah 48V battery will provide 21 amps for one hour at approximately 48 volts, or 7 amps for 3 hours etc.
What does watt Hours (Wh) mean for eBike batteries?
Watt hours (Wh) is a very common eBike battery spec and is calculated by multiplying the amp hours (Ah) by battery voltage. Watt hours is basically the number of watts that can be delivered in one hour. The Electrified Mobile long range 21Ah 48V ebike battery would be 1008Wh. If you use this battery with a 500W motor and ran it non-stop at the highest level of assist or full throttle, you’d get about two hours of use. Most cyclists assist the motor by pedalling, so the motor would only need to partially assist the rider. In this case, if we were only using an average of 250W this battery would last approximately 4 hrs and so on. Please note that the weight of the rider, terrain, etc. would affect this as well.
What is the advantage of eBike hydraulic brakes vs mechanical ?
1.Stopping PowerHydraulic brakes tend to have better stopping power than mechanical brakes. This is because hydraulic pressure will multiply the power applied to the brake handle through pressure applied to the brake pads from the caliper. In comparison, mechanical brake power is directly applied through a cable to the brakes where the force is reduced due to drag between the cable and housing.

2. Precision and Control of braking – Hydraulic disk brakes give you greater control when braking your eBike. This is because only a small amount of pressure is required when squeezing the brake levers which helps to provide the desired braking force required.

What are the advantages of rear hub motors and mid drives?

Rear hub drives run independently of the mechanical drive system so they do not add stress to the chain or drag to the system. For this reason, the rear hub system is much more forgiving and can be pedaled normally without using the motor. In addition, if you ever break a chain, you can still ride home using motor power.  In mid drive motor eBikes, the chain needs to rotate in order for the rear wheel to turn and all the torque from the motor is placed on the chain. The advantage of this is that all the mechanical gears of the cassette are used which can give you more torque and flexibility if used correctly. With mid drive electric bikes riders need to make sure they are in the correct gear based on speed or terrain. If shifting gears at the wrong time, they can easily break the chain. This is especially true when shifting on steep inclines. If a chain breaks on a mid drive it will need to be replaced before you can drive the bike again.
